In the drawings, whereinlike characters of reference designatecorresponding parts, 1 indicates a suitable valve casting formed with a,cylindrical chamber '2 horizontally disposed therein and surrounded by asuitable wa11'3, the chamber being closed at its ends by suitable endplates 4. From opposite sides of thechamber 2, and connected with thewalls 3 thereof, extend the wall members 5 preferably flanged at theiredge, as at 6, providing shells and 8 at opposite sides of the valvechamber 2 and wlth each of which coiiperates the respective chambers 9and {10, the chamber 9 being any suitable conventional form of cookingchamber, and the chamber being any suitable form of cooling chamber. Theedges of the chamber forming walls are secured in any suitable manner tothe flanges 6 of the chambers 7 and 8. Within each chamber 9 and 10 isprovided a suitable endless rece tacle conveyer, a portion of each ofsaid conveyers being articularly illustrated in Figs. 1 and 2 0? thedrawings, and each consists preferably'in a horizontal flight 11 and avertical flight 12, which are interconnected, forming complete endlessconveyers in the respective chambers. The respective conveyers areformed with the transversely disposed conveyer bars 13, on which thereceptacles rest, and which m; secured at their ends to end plates 14,said plates carrying on their extremities a pair of'members 13receivable at their ends in heads 15 operating in grooved tracks orrails 16, the heads 15 in the respective tracks or rails being separatedby the contact of adjacent edges of the end plates 14.

Each of the conveyers 11 at the point of intersection of the verticaland horizontal ticular form being. illustrated in the presentdisclosure. 7 I 7 Within the valve chamber 2 is .rotatably mounted ahorizontally disposed transfer valve'20 of. a length less than that ofthe chamberv2, as illustratedin Fig. 30f the r drawings, and theperiphery. of said valve is adapted to contact with and bear on theinner surfacesof the annular valve supporting flanges 21 disposed atopposite ends of the respectiveopeningslS and 19 and particularlyillustrated in Fig. 3 of the draw ings. The valve ,20 is providedon itsperiphery with a plurality of receptacle cham hers 22 of a length.corresponding to the openings, 18and19 and ofa depth and sizesufiicient to Y receive a row of receptacles to be transferred-gintheapparatusa 1Th'e'valve20 at one end carries a plate 23 into whichpassesasuitable bolt 24 forming a bearing, the bolt having an enlargedsurface 25 which is received in a bearing 26 pos tioned w1th1n thechamber2ad acent one end, this construction precluding longitudinalmovement of the valve20, in onedirection within its chamber 2. NVithinthe opposite end of the chamber '2 is positioned a suitable ring 27, thesamein its face adjacent the valve end being provided with a cam groove28, Figs. 3' and 6 of the drawings.

"Inthiscam groove 'operate'a plurality of rollers 29, each carried on alever 30 -fulcrunied asat31- to the end of thevalve, and said. levers,attheir outer ends, being pro-v vided with racks 32 engaging pinions 33on the ends of shafts 34, each of said shafts extending longitudinallywithin one of the chambers .22 adjacent the terminal edge of.

its sidewall, as in Figs. 1" and 2 ofthe drawings.

wdinal movement of thevalve 20 in one direcmarily for ejecting thereceptacles at predetermined timed intervals from the respectivechambers for the hereinafter described purpose.

The ring 27 precludes longitu operate the same in the direction of thearrows by a suitable vertically disposed shaft 36 carrying a worm 37which engages with a worm gear 38 formed on the periphery of the disk23, Fig. 30f thedrawings, and said shaft 36 at its upper end carries abeveled gear 39 driven by a bevel pinion 40 on a power shaft 41preferably 'dlSPOSEd at right angles to the shaft 36 and extendinghorizontally from one end of the casting 1, said shaft 41 being providedwith a bandwheel 42 on its outer free end, as in Fig. 5 ofthe drawings,for receiving ower'transmitted thereto to rotate the sha t in. thedirection of the arrow, Fig. 5 of the drawings.

Receptacles to be transferred by the valve 20 are fed to and removedfrom the valve casing 1 at a point intermediate the openings 18 and 19by a'vertically disposed endless conveyer 43 similar to the conveyers 11in the chambers 9 and 10, and said conveyer 43 at its point ofconnection between parallel flights thereof communicates with theinterior of the chamber 2 through a receptacle feed and dischargeopening 44'. This con veyer, like the conveyers 11, is operated, in thedirection of the arrows, in timed relation with the rotation of thevalve20 by any suitable formof mechanism, not shown in the drawing. saidconveyer 43 are con The receptacles carried by ned between suitableguide plates 45 and 46 connecting at 7 their lower ends with the sideedges of the opening 44, as'in Figs. 1 and 2 of the drawings. Thedistance between the side edges of the opening 44 and the adjacent edgesof the respective openings 18 and 19 is slightly greater than the widthfrom top to bottom of the openings of the respective chambers 22 so thatno direct communication is had between the respective openings 19- and44 and 44 and 18 through the respective chambers 22.

The cam surfaces 47 of jthe'groove 28' respective conveyers andpermitting the feeding of different receptacles from the conveyers andto be received within the chambers from which the receptacles were justpreviously discharged.

To more fully comprehend this action, f reference is directedparticularly to Figs. 1'.

and 2, wherein the row of receptacles 47 from the conveyer 43 have beendischarged from their supporting rods 13'on' the passage of the endplates thereof from one flight of the conveyer to the other, and arepartially received within one of the chambers 22, the return of theplate 35 to the base of the chamber arresting the downwardmovemant-ofjhe row of receptacles 47. After being fully reoeivedwithinthe chamber 22, the row of-reoeptacles 4?, as in Fig. 2 Ofthedrawingsyiis gradually transferred by the a rotaticncf the valv'e flt)from the openi 44 to the 18511 which time the pfiate awociatediiwiti thechamber containin the rowflf, receptaclwel is swnn outward y todischarge-the row} of .reeeptac es 47 onto the rodslfioi one loilthesections of the conveyer 11 in the cooking chamber.

he plate A8 is mounted on a shaft 49 fulcrumed at its endsin bearings50, the end ofaaid shaft ca i'ng a crank portion 51 to which is pivolyconnected one end of an operatingrod52, said rod at its lower endcarrying a casting 53 forked at its terminal end as at 5;. The forkedterminal end 54 of the L53 straddles a shaft 55 dis- I 80? osedtransversely of the valve casting 1 beowand atlone side of the valve 20,as in Fi 2 and.-3 ofthe drawings.

fine; shaft 55 carries a disk 56 having cam surfacest? which are adaptedon the rotation of the disk to coact with a cam roller 58 on the. castin53 and impart a swinging movement to e plate 48 through the rod 52. Theshaft 55 is sup rted in suitable bearings 59 and at its en removed fromthe disk 56*- carriesa 'worm gear 60 which intermeshes with. and isdriven'in the direction of the arrow, Fig. 4!, a worm 61 on the shaft36. The swizngmg 0 the plate 48 by the rotation ofuthe shatt 55, whichis operated in timed relationwith' the movement of the conveyer 11 inthe chamber -9 and with the rotation of the valve 20; receives a: row ofreceptacles or containars as the same arrive at the offset point-62ofgthevertical flight of-said con- "11,- and during it'sswingingmovement sandl'plate addeposits the receptacles into the unhocupiadehamber22ofthe valve 20.

:Thedeliieringcf thereceptacles from the offset, portioh 62erthcwerticalflight of the conveyer ii in thechamber9 is made possible owing tothereceptacles resting on the barsorrods 13,and these rods in their path oftravel assuming a position transverse to the 16 at said offset portion.

1 The receptacles astransferred by the valve 201mm the chamber 9 to thechamber 10 are discharged from their respective chambers on the chamberarriving in register with the openin 19,- this discharging action beingbifaecomp ished hy the formation oi the cam groove 28 which causes aswinging of the ejector plates 35 outwardly as the respective chamberssuccessively register with said opening 19. The processed containers orreceptacles as discharged from the respective chambers, are depositedonto the bars or rods 13 of the conveyer 11 in the chamber 10 as thebars arrive at the upper end of the vertical flight of said oonveyersand rest thereon during their travel through the pressure coolingchamber 10 until they are returned to the terminus of the horizontalflight adjacent the opening 19. When in this position the chambers 22from which receptacleshave been previously discharged are immediatelyre-supplied with receptacles in a cooled condition and which have beenconveyed through the chamber 10, the mechanism for performing saidoperation being preferably constructed as follows Immediately above theopening 19 in the wall of the valve casting 1, I rovide a pocket 65communicating at its ower end with the interior of the chamber 10, andmounted in the pocket is a suitable frame member, the legs 66 of whichare longitudinally slotted as at 67 adjacent the lower end. Connectingthe lower ends of the legs 66 is a suitable blade 68 adapted formovement in an ovular path to and from the forward end of the horizontalflight of the conveyor 11 in the chamber 10. The legs 66 in the downwardmovement of the blade 68 are ada ted to be inclined rearwardly as inFig. 1 of the drawings, and said blade on reaching its lowermost pointof travel is adapted to pass in rear of the receptacles at the forwardend of the horizontal flight of the conveyor 11, in chamber 10 and toadvance said receptacles at a speed slightly faster than the travel ofthe conveyor 11, moving the receptacles from their supporting rods 13 toa position to rest on the supporting rods 13 in advance thereof, whichhave passed from the horizontal flight on to the vertical flight of saidconveyer 11 in the chamber 10, this position being illustrated in Fig. 1of the drawings.

The continued forward movement of the blade 68 removes the receptaclesfrom their supporting rods 13 and deposits the same into the emptychamber 22 from which has just been delivered receptacles to thevertical flight of the conveyor 11 of the chamber 10, this action takingplace on the rearward movement of the blade 35 in the empty chamber 22.The continued movement of the blade 68 after delivering the receptaclesto the chamber 22 is in an upward and rearward direction, as illustratedin Fig. 2 of the drawings. The mechanism for operating and controllingthe movement of the blade 68 and its associated legs 66 comprises ahori-' zontally disposed rod 69 extending transversely of the pocket 65,and through the slot 1 67 in thelegs providing a fulcrum for the frame.The upper ends of the legs 66 are fulcrumed to rotate about a crankframe 70 supported on a sha-ft71 rotatable in bearing-s72 and said-shaftat its end carries a worm gear 73 driven inthe direction of the arrow,Fig. 4, by ,a worm gear 74 on a rotatable shaft? 5, one end of whichextends over the shaft 41 and carries a, worm gear 76 which is driven bya worm pinion 7 7 on the said shaft 41, as illustrated in Fig. 4 of thedrawings.

It will: be apparent from the description and an examination of thedrawings, that power applied to the band wheel 42 drives the shafts 41,36, 55 and in unison, and at theiryproper speeds to obtain a properworking of the apparatus with all. parts operating in timed relationrelativelyto each other.

The receptacles as delivered to the chamber 22 by the blade 68 areelevated by a rotation of the valve 20 until they register with theinlet and discharge opening 44, at which time the member 35 of thechamber in register with sai'dopening is operated by the formation ofthe cam groove 28toraise the receptacles from their. associated pocketor chamber and into the path of the conveyer 43, the dischargedreceptacles being received between the unoccupied rods 13 of theconveyer section, from between which receptacles were delivered to apreceding chamber immediately before thepresent discharge operationtakes place.
